Quest 506 is the industry's first 500 pint, 230 V 1 phase, commercial dehumidifier designed for commercial growing at scale. Like all Quest products it can be placed at ground level for immediate operation or hung overhead and out of the way. The Quest 506 is the most energy-efficient, high-capacity dehumidifier on the planet, using minimal Amps (11) and maximum efficiency (8.1 pints/kWh). It is made in the USA. Optional condensate pump and ducting kits provide the ultimate flexibility for the most challenging space restrictions and specialized applications. MERV-11 filtration is standard on these units, capturing particles (including mold spores) down to 1 micron in size. An additional Humidistat is required; we recommend the DEH 3000R Wall Mounted Unit #700833. Warranty: 1 year parts and labor. 5 year compressor and refrigerant system.
